2x = -18 Divide by 2
x = - 18/2
x = -9
Answer:
Total cards in a deck=52
Face cards =12
So probability of picking a face card is 12/52=3/13
Step-by-step explanation:
Usually there are 12 face cards in a group, so that would be 12/52 -- but wait! You can simplify, always. check. for. simplifying. possibilities.
Usually in an answer they will include both simplified, and not simplified. Believe it or not, usually they ask for the simplified. Make sure you read carefully.
Answer:
1. 4.25
2. 8.75
3. 8
Step-by-step explanation:
Yes, it’s a function because there is no repeating x-values,
Replace x and y’all with the point and solve the equations
1. 2(0.5)+ 4(-6.75) = 1 + -27 = -26
This is true so is an answer.
2. Y = 0.5-7.5 = -7, -7 is not -6.75 so this is not true.
3. 2(-6.75) = 0.5 + 13
13.5 = 13.5
This is true so is also an answer.
4. -6.75 = 0.5(0.5) -7
-6.75 = 0.25-7
This is true so also an answer.
